In saline soils, banana suffered from salt injury with the external symptoms. The caroteniod content was decreased in all the treated plants except in control. In all the NaCl treated plants the chlorophyll pigments was significantly reduced. In abscissic acid(ABA), treated plants chlorophyll content was significantly increased. Membrane Stability Index(MSI) was decreased when the salt stress period increased. In case of Cholorophyll Stability Index(CSI) and Membrane Stability Index(MSI), the butylated hydroxyl toluene(BHT) increased over the other chemicals treated in NaCl stress, where as in acetyl salicylic acid (ASA) increased MSI only. The ASA capable of inducing more ascorbic acid production in more NaCl stressed plants. Peroxidase and superoxide dismutase activities were decreased significantly over the period of stress increases. In BHT treated salt stressed plants observed significantly higher nitrate redcutase activity. The persent investigation showed that the abscissic acid(ABA), acetyl salicylic acid (ASA) and butylated hydroxy toluene (BHT) have the potential to reverse the effect of salinity in Grandnain banana plants.
